I had my period 2 weeks ago and the it finished with brownish discharge a week later, since then for the past week I don't bleed during the day but after we have sex I bleed, it is quite a lot and bright red. Ive got a swab booked for Monday to test it but I am very worried. Could it be as simple as a tear as my husband is in the army and has only been back from canada for a few weeks so there was 5 months I didn't have sex now its everyday and sometimes rough. Could that be a reason? The nurse said it the 2 big possibilities are cervical erosion or chlamydia but I don't know? How would I have got them?
